Khorat used to be the site of several ancient prehistoric communities. Little is known about the early history of Khorat, except that it used to be part of a kingdom called Sri Janas (Si Janat) an empire that extended its power to the entire Khorat Plateau.
Initially the predominant cultural influence in the city was that of the Dvaravati culture, however, it was later replaced by the Khmer culture. The prehistoric site of Ban Prasat is an evidence of this occurrence while traces of both the Dvaravati and Khmer cultures are scattered throughout the province, particularly at Amphur Sung Noen and Amphur Phimai.
Once an administrative and cultural center, Khorat's role today remains unchanged as it is currently the main transportation, industrial and economic hub of the Northeast.
